The idea behind the emerald was interesting, but there's just too much sex going on. I know this is erotica, but having the characters doing it over and over on the beach all in one day is a bit much for me. It was also weird when the guy started to put chocolate the woman's private parts. Like even inside her... They also apparently did it in the ocean. It wasn't clear though whether they were underwater or what since the author doesn't describe the scene very well.
